In commit 49edde15230a ("OvmfPkg/PlatformPei: set 32-bit UC area at
PciBase / PciExBarBase (pc/q35)", 2019-06-03), I forgot to update the

OvmfPkg/VirtNorFlashDxe: map flash memory as uncacheable
Switching from the ArmPlatformPkg/NorFlashDxe driver to the
OvmfPkg/VirtNorFlashDxe driver had the side effect that flash address
space got registered as EFI_MEMORY_WC instead of EFI_MEMORY_UC.
That confuses the linux kernel's numa code, seems this makes kernel
consider the flash being node memory. "lsmem" changes from ...
RANGE SIZE STATE REMOVABLE BLOCK
0x0000000040000000-0x000000013fffffff 4G online yes 8-39
... to ...
RANGE SIZE STATE REMOVABLE BLOCK
0x0000000000000000-0x0000000007ffffff 128M online yes 0
0x0000000040000000-0x000000013fffffff 4G online yes 8-39
... and in the kernel log got new error lines:
NUMA: Warning: invalid memblk node 512 [mem
0x0000000004000000-0x0000000007ffffff]
NUMA: Faking a node at [mem 0x0000000004000000-0x000000013fffffff]
Changing the attributes back to EFI_MEMORY_UC fixes this.
